Hi all, I have just optimized a human model that had around 150 individual GL_LINE_STRIP drawables by adjoining these. This requires doubling the last vertex of a strip and the first vertex of the next strip which is to be appended, generating a couple of degenerate triangles.
The model still renders fine and the OSG stats viewer now shows a much lower drawable count. A quirk appears when rendering this in wireframe mode (using the 'w' hotkey implemented in one of the builtin Event handlers). I assume this enables a GL PolygonMode of GL_FRONT_AND_BACK, GL_LINE. Now the degenerate triangles are still rendered, making the model look broken (arms look fused to the body). Here's my question: Shouln't wireframe rendering mode hide degenerate triangles, as they wouldn't be passed on to the rasterizer in any case?
